A documentalist is a professional, trained in documentation science and specializing in assisting researchers in their search for scientific and technical documentation. With the development of bibliographical databases such as MEDLINE, documentalists were professionals who searched such databases on the behalf of users.

When the field of documentation changed its name to information science, the terms information specialist or information professional often replaced the term documentalist.
